{"id":"GHSA-r88h-6987-g79f","summary":"Duplicate Advisory: Data races on syncpool","details":"## Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-vp6r-mrq9-8f4h. This link is maintained to preserve external references.\n\n## Original Description\nAffected versions of this crate unconditionally implements `Send` for `Bucket2`. This allows sending non-Send types to other threads.\n\nThis can lead to data races when non Send types like `Cell\u003cT\u003e` or `Rc\u003cT\u003e` are contained inside `Bucket2` and sent across thread boundaries. The data races can potentially lead to memory corruption (as demonstrated in the PoC from the original report issue).\n\nThe flaw was corrected in commit `15b2828` by adding a `T: Send` bound to the `Send` impl of `Bucket2\u003cT\u003e`.","aliases":["CVE-2020-36462","GHSA-vp6r-mrq9-8f4h","RUSTSEC-2020-0142"],"modified":"2026-02-03T03:07:50.215416Z","published":"2021-08-25T21:00:28Z","withdrawn":"2026-01-23T22:52:22Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-362"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-08-05T22:09:21Z"},"references":[{"type":"WEB","url":"https://github.com/Chopinsky/byte_buffer/issues/2"},{"type":"WEB","url":"https://github.com/Chopinsky/byte_buffer/commit/15b282877d1e576de2b337d8162bbf43ed1a0f2d"},{"type":"PACKAGE","url":"https://github.com/Chopinsky/byte_buffer/tree/master/syncpool"},{"type":"WEB","url":"https://github.com/RustSec/advisory-db/blob/main/crates/syncpool/RUSTSEC-2020-0142.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0142.html"}],"affected":[{"package":{"name":"syncpool","ecosystem":"crates.io","purl":"pkg:cargo/syncpool"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.1.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-r88h-6987-g79f/GHSA-r88h-6987-g79f.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
